Question

mensuration all the formulas and units ?

Answer 1

Area of rectangle= l×b
Area of square= side side
Trapezium= (a+b)h/2
Triangle= 1/2×b×h

Volume
Cube= a^6
Cuboid= lbh
Cylinder= 2πrh

Answer 2

area of triangle = 1/2×b×h
area of rectangle = a×b
area of square = side × side
area of parallelogram = b×h
area of circle = πr^2
area of semicircle = 1/2πr^2
curved surface area of cylinder = 2πrh
total surface area of cylinder = 2πr(r+h)
area of trapezium= 1/2×sum of parallel sides×distance between the parallel sides
area of Rhombus=1/2×product of its diagonal
volume of cuboid = l×b×h
volume of cube = (length of an edge)^3
Volume of Cylinder = πr^2h
lateral surface area of cylinder = 2πrh
surface area of cuboid = 2(lb+bh+lh)
surface area of a cube = 6(length of an edge)^2
area of four walls = 2(l+b)h
lateral surface area of a cuboid = 2(l+b)h
lateral surface area of a cube = 4(length of an edge)^2
